Abstract: PURPOSE:To continuously cut a groove having the same depth almost free from an error and to markedly enhance the capacity of a product by cutting a plurality of grooves having a required depth at a required interval by a blade not absorbing a cutting fluid and showing no change in its diameter. CONSTITUTION:An object 11 to be processed is held to a predetermined holding means 12 and a disc-shaped blade 14 cutting the surface of the object 11 to be processed to form grooves 13 is mounted to a drive shaft 15 and a cutting fluid supply means 15 for supplying a cutting fluid to a region to be cut is mounted. By allowing the blade 14 to act on the object to be processed, the grooves 13 are cut continuously and successively.
